Transparent molded objects, optical member, plastic lens, and processes for producing these |
摘要 |
<p>A transparent molded article comprised of a polymer of the following components (A) and (B), characterized in that said polymer further comprises the following components (C) and (D). A transparent molded article comprised of a polymer of the following components (A) and (B), characterized in that said polymer further comprises the following component (G). An optical member comprising an antireflective layer directly or indirectly on a polyurethane urea polymer substrate, characterized in that said antireflective layer is a multilayer antireflective layer comprising a 1/2 » layer, and said 1/2 » layer comprises a plural high refractive index layers comprising niobium oxide or niobium oxide, zirconium oxide and yttrium oxide, and a layer comprised of silicon dioxide positioned between the high refractive index layers.
Component (A): isocyanate terminal prepolymer in the form of a reaction product of an aliphatic diisocyanate having an intramolecular cyclic structure and a diol having an average molecular weight of 300-2,500
Component (B): one or more aromatic diamines denoted by general formula (I). (In general formula (I), R 1 , R 2 and R 3 are each dependently any of a methyl, ethyl or thiomethyl group.)
Component (C): one or more phosphoric acid monoesters denoted by general formula (II). (In general formula (II), R 4 is an alkyl group with a carbon number of 1-10 and n 1 is 1 or 2.)
Component (D): one or more phosphoric acid diesters denoted by general formula (III). (In general formula (III), R 5 and R 6 are each dependently an alkyl group with a carbon number of 1-10 and n 2 and n 3 are 1 or 2.)
Component (G): one or more phosphorous peroxide decomposing agents.</p> |
